App1ication filed June 5,1914. Serial No. 843,180.

To all whom it may concern."

Be it known that I, GAETANO Frgs'm, a citizen of the United States, residing at Re- Vere, in the county of Suffolk and State of lVlassachusetts, have invented certain new and useful Improvements in Air-Motors for Fans for Railroad-Cars, of which the following is a specification.

This invention relates to fans for railroad cars, street cars, and auto vehicles, and one of the principal objects of the invention is to provide a fan for ventilating and cool ing purposes in cars, and other vehicles, and to provide simple and inexpensive means for running the fan.

Another object of the invention is to provide a fan to be located within the car or vehicle and means for operating said fan comprising a wind wheel connected to the shaft of the fan and located outside the car to be rotated by the movement of the car or other vehicle for operating the fan.

These and other objects may be attained by means of'the construction illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation and partial section of a fan and means for operating the same, made in accordance with this invention. Fig. 2 is a top plan View showing one of the blades of the wind wheel and the manner of securing it in a diskat the top of a car above the rope thereon, Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1 looking in the direction indicated by the arrow, Fig. 4 is a sectional view taken on the line 44 of Fig. 1, Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 1, Fig. 6 is a detail longitudinal sectional view showing the manner of connecting the fan blade, Fig. 7 is a detail sectional view showing the bearing for the fan shaft, and Fig. 8 is a bottom plan View of the disk for holding the blades of the wind wheel.

Referring to the drawings, the numeral 1 designates the top or roof of the car 01 other vehicle, and extending through an aperture in the roof is a Shaft 2 of rectangular. cross section, said shaft being mounted within a tube 3 extending through the top of the car. Mounted on the shaft 2 is a disk 4 having peripheral apertures 5 to receive the shank 6 of the wind blades or vanes 7. Binding screws 8 extend into t set screw 9 serves to hold disk 4 on the shaft 2. The blades or vanes 7 of the wind Wheel are angular in cross section and bent out of the plane of the blade at the centrallongitudinal line 10, as shown more clearly in Fig.4 of the drawings.

The upper end of the tube 3 bears against the underside of the disk 4 and extends into the car. Secured underneath the roof 1 of the car is a bearing tube 11 secured in place by a bolt 12 at its upper end and provided with a binding screw 13 which bears against the tube 3 to hold the latter rigidly in place and to permit the shaft 2 to rotate therein.

The shaft 2 is hollow and at its lower end is fitted a squared shank14-provided with a shoulder 15 and an extension 16 of substantially the same dimensions as the shaft 2, and connected to said extension. 16 by means of a screw 17 are the planes 18 of the rectan ular bearing portion 19 in place.

The shanks 18 are connected to the fan blade 20 by means. of bolts 21 provided with washers 22 and nuts 23, as shown more clearly in Fig. 5, the blade 20 being pro vided with lugs 24, which bear against one side of the shank 18 to givestability to the blade. Theblades 20 are also bent outward upon one side of the fiat plane at the central longitudinal point 25.

Extending downward from the extension 16 is a rod 26 which extends through abearing tube 27 and into a ball or sphere 28.

The tube 27 is threaded in the ball 28 as shown in Fig. 6, and the lower end of the rod 26 is tapered off to apoint, as shown at 29 and mounted in a bearing socket 30 within the ball 28. Connected at four points tothe ball 28 are supporting members 31,

which inclose the fan blades 20 and are provided with vertical members 32, the upper ends of which are secured by means of bolts 33 underneath the roof of the car and inside the same.

, From'the foregoing it will be obvious that V tails of construction without departing from 1 Y the spirit and scope of the invention as defined in the claim.

What is claimed is A fan comprising a central disk or hub, saidLdisk being provided with peripheral pockets, fan blades, shanks secured to said blades, said shanks being adjustable in the pockets in the disks, a rectangular shaft on which said disk is connected, a rod connected to said shaft and mounted to rotate in the bearing, said rod having a pointed end, said bearing comprising a ball having a tapering bearing socket therein, fan blades mounted on said rod, and a frame connected to said ball and to the other side of a roof of a car.

In testimony whereof I afiix my signature in presence of two itnesses.
